fuel question answered!
« on: September 26, 2024, 12:46:15 PM »
I've always wondered how much fuel was left in the hose from the previous user at a gas station (on the typical new pump with 1 shared hose for multiple grades of fuel). Turns out it's much less than I thought...only about 30 oz of fuel. (looks like full link didn't load, it is a youtube video from Ari Henning, the Shop Manual, Revzilla)

simple volume calculation (R squared x pi x length of hose = volume)  7.48 gal/ cubic ft. extra long hose might get you 1/3 gallon. piping calculations were common in my career before I retired

I never knew where the splitting valve was...was it deep underground or was it in the pump? Per this video the valve that splits the different fuels is in the top of the fuel pump, making a much shorter run to eliminate the non wanted gas.

Once, at 18, when I was on my 3rd cross-country hitch-hiking adventure I distinctly remember the two guys in a beat-up van who stopped for me late at night outside of Vegas.
They were stopping at passing gas stations and getting the gas out of the hoses.....then I saw one guy stealing quarts of oil from those racks near the gas pumps while the other guy kept the clerk busy. Remember those racks?

I got my guitar and backpack out, thanked them for the lift....and hiked down the road before we all got arrested.
I also remember this - I came upon a city park. Nice grass. I stretched out under a tree. Went right off to sleep....to be rudely awakened by an auto sprinkler system kicking on about 5 AM!

That night, it was like midnight, looking down there at all those crazy bright lights from an on-ramp at the edge of town - was the closest I ever got to Vegas.
So, when people ask, "you ever seen Vegas?"
"Well, I sure have!"

Some 'rides' you never forget!
One time: my ride was out of San Diego - two sailors towing a 57 Chevy and a trailer. Going to Kansas City. "Can you take a turn at driving through the night, kid? "
Sure I can, I'm an American 18 yr old. (I rode motorcycles - the last time I'd driven a car I was 12. My grandmother used to toss me the keys and send me for eggs at the farm up the road) They went to sleep and I didn't kill us all that night.

And, I'm feeling a little peculiar.
